A diffuser/nozzle pair serves as a flow rectifying element in a valveless micropump, which is one key component in microfluidics devices. This paper proposes a diffuser/nozzle element with extended sidewall, ‘lip’, at the diffuser’s large opening end. This novel structure is based on the fluid mechanism concept that an extended sidewall introduces extra entrance pressure loss, which is preferred in...
AbstractThe effect of lateral mass flux on mixed convection heat and mass transfer in a saturated porous medium adjacent to an inclined permeable surface is analyzed. A similarity solution is obtained when surface temperature and concentration, free stream velocity and injection/suction velocity of fluid are prescribed as power functions of distance from the leading edge. The cases when the flow and...
